Not leaving home alone would be the agoraphobia aspect of PTSD. "Normal" Not doing house hold chores would likely be the depression aspect, again normal. Knitting, she found something to zone out on and relax, not a bad thing. Being detached emotionally (like the babies) is also again normal and could also be due to depression. The things that do not seem normal for PTSD is the hand switch and memory.

The therapist is fine with a PhD. who has experience with trauma and is 10x better than a shrink who passes dope out like candy, though there is a need for meds they can get a bit silly with them sometimes. I get stuffy as my shrink messed up meds and landed me in the hospital. As far as the therapy and trying to heal from the trauma the PhD is a lot better as they coach you, shrinks don't. My shrink rarely sees me except to try and find a new pill to fix me, my other doc was weekly and he used CBT.

Plus side though the shrink will be a MD so you have a better chance if you find a good one at finding out where these other symptoms your wife has are coming from. The Phd is going to work more on your cognitive behaviors though. But if she cannot remember the last session you are throwing money out the window until she gets her memory straight. I thought I would never say this. But I think the MD shrink would be your best choice for now. It seems obvious your wife needs meds at this point and you need a medical doctor for her condition as it now stands. Once she gets a grip on memory then therapy would be useful and needed. Then reintroduce the (new) PhD person.

But the PhD your wife sees weekly for 6 months now... I think I would want to knock the hell out of. If her condition has been unchanged and like it is now for 6 months they are taking you for a ride and should have told you months ago she needs an MD and they cannot help her the way she is currently. Therapy is useless if you cannot remember the skills they are teaching you. I think that doc sees $$$... not the problem your wife needs help with.
